Displacement Channel

The Displacement channel controls the surface roughness. While the settings are similar to those used in a Bump map, there is one key difference. Unlike the bump channel, displacement affects the underlying geometry of the surface. This means that the edges of the surface will also look rough.

You have the following options when working with the displacement channel:

  • Strength: When a bump map is selected, the Bump Strength slider controls the strength of the bumps, or how rough the surface appears. A setting of 0% means that the bump map will have no effect on the surface. A setting of 100% means that the bump map will have full effect on the surface.

    If no displacement map is selected, i.e., the texture selector indicates “None,” then the slider will not be visible. Select a texture and the slider will be displayed.
  • Image Menu: To assign a grayscale texture map as a displacement map, click on the field to display a menu where you can select a texture from the list or browse for a new texture. A menu prompts you to browse for a new image and displays images that are already present in your scene.
  • Minimum: This setting provides a “low cutoff” setting for the lower areas of your displacement map. If the setting is too high, it can cause your geometry to appear much distorted and increases render time.
  • Maximum: This setting provides a “high cutoff” for the higher areas of your displacement map. If the setting is too high, it can cause your geometry to appear much distorted and increases render time.
